Boat inspection ports. I have used these before. They work well and have reasonable durability for their price.

I installed the plate 6 months ago in a fresh water tank. Looked good, worked fine. I tried to open it today to rinse out and sanitize it for a trip in about a week. Can't get it to unscrew. It is not cross threaded, just seized up tight. I didn't see any instructions to lube the threads. I've sent a message to West Marine. I hope there is a way to open this without destroying it. Maybe I can get some food grade grease or oil down in the threads. I don't want to have to cut out the whole flange.

The coarse threads on the lid will not make a flush fit. Tried to uee on a boat water tank as a port for cleaning. The product design is defective and impossible to stop even heavy leakage. Will never recommend.

I recently replaced all the deck plates on my boat with the "West Marine Screw-in Deck Plate, 6, Smooth, White". These are much thicker and stronger than the originals, and they are made of a much more UV resistant material. I expect these to continue to look good and to perform well for many years to come.
